Maths (Arithmetic): MLS2 (Disc version)

Name: MLS2 [View in context] Type: Subroutine Category: Maths (Arithmetic) Summary: Calculate (S R) = XX(1 0) and (A P) = A * ALP1
Calculate the following: (S R) = XX(1 0) (A P) = A * ALP1 where ALP1 is the magnitude of the current roll angle alpha, in the range 0-31.
.MLS2 LDX XX \ Set (S R) = XX(1 0), starting with the low bytes STX R LDX XX+1 \ And then doing the high bytes STX S \ Fall through into MLS1 to calculate (A P) = A * ALP1
